Definitions
- the present invention relates to a winding method and structure for stator coils and, more particularly to a novel improvement according to which each stator coil is wound in series around a plurality of ones of the coil bobbins provided on the stator teeth body to form coil end portions at both ends, whereby it is possible to achieve a reduction in the number of coil end portions coming out from the stator coils and an improvement in operational efficiency in soldering or the like and in quality.
- FIGS. 4 through 8 show a conventional winding method and structure for a stator coil of this type.
- numeral 1 indicates a stator teeth body which has a ring-like general configuration and a plurality of (nine) stator teeth 2 and which is formed through lamination in the axial direction, a cylindrical coil bobbin 4 with a stator coil 3 wound thereon being fitted onto each stator tooth 2 .
- stator teeth body 1 whose stator teeth 2 are equipped with the coil bobbins 4 is forced into the interior of an inner wall 5 a of a cylindrical stator yoke 5 , and the stator teeth body 1 and the cylindrical stator yoke 5 constitute a stator 10 .
- a ring-like printed board 11 constructed as shown in FIG. 8, and, in the outer edge of this ring-like printed board 11 , there are formed eighteen terminal patterns 1 A through 18 A.
- Pairs of coil end portions 3 a and 3 b constituting the coil ends of the stator coils 3 wound around the bobbins 4 are respectively soldered to the terminal patterns 1 A through 18 A.
- the terminal patterns 1 A through 18 A are constructed for driving in the three phases of U-phase, V-phase, and W-phase.
- the conventional winding method and structure for a stator coil, constructed as described above, have the following problem.
- stator coils wound around the coil bobbins are independent of each other, it is necessary to solder the eighteen in total of coil end portions to the terminal patterns of the printed board, with the result that the soldering operation requires a lot of manpower and cost.
- the present invention has been made with a view toward solving the above-mentioned problem. It is particularly an object of the present invention to provide a winding method and structure for a stator coil in which a stator coil is wound in series around a plurality of coil bobbins of the coil bobbins provided on the stator teeth body to form coil end portions at both ends, whereby it is possible to achieve a reduction in the number of coil end portion lead-outs of the stator coil and an improvement in operability in soldering or the like and in quality.
- a stator coil winding method in which coil bobbins having stator coils are provided on a stator teeth body formed in a ring-like general configuration and having a plurality of outwardly protruding stator teeth and in which the stator teeth body is mounted to a cylindrical stator yoke, characterized in that each stator coil is wound continuously and in series around a plurality of coil bobbins of the coil bobbins to form a series winding stator coil body, and the series winding stator coil body has at its ends a pair of coil end portions.
- the stator coil winding method has such a structure that: each series winding stator coil body is formed by three coil bobbins; three such series winding stator coil bodies are provided; and each stator coil is wound around the three coil bobbins of each series winding stator coil body, with the coil bobbins being penetrated by and arranged at intervals on an elongated bar-like winding frame jig.
- the structure in which coil bobbins having stator coils are provided on a stator teeth body formed in a ring-like general configuration and having a plurality of outwardly protruding stator teeth and in which the stator teeth body is mounted to a cylindrical stator yoke, the structure is characterized in that a series winding stator coil body formed by winding stator coils around a plurality of coil bobbins of the coil bobbins in series and continuously is provided, and a plurality of such series winding stator coil bodies are provided on the stator teeth body.
- FIG. 1 is a schematic diagram showing winding using a winding frame jig applied to a stator coil winding method of the present invention
- FIG. 2 is a schematic diagram showing how coil bobbins which have undergone winding by using the winding frame jig of FIG. 1 are mounted to stator teeth;
- FIG. 3 is an exploded sectional view showing the stator teeth body of FIG. 2;
- FIG. 4 is a schematic diagram showing a conventional stator teeth body
- FIG. 5 is an exploded sectional view of FIG. 4;
- FIG. 6 is a schematic diagram showing how a stator teeth body is inserted into a cylindrical stator yoke
- FIG. 7 is a schematic diagram showing connection between stator coils of a conventional stator teeth body and a ring-like printed board.
- FIG. 8 is a plan view of the ring-like printed board of FIG. 7 .
- FIG. 6 which is applicable to the present invention, will be referred to in the following description.
- FIG. 1 shows an elongated bar-like winding frame jig 20 developed particularly for this invention.
- Three coil bobbins 4 are detachably mounted to the winding frame jig 20 at a predetermined interval D.
- a stator coil 3 is wound around the coil bobbins 4 in the order: A, B, and C of FIG. 1 . That is, the stator coil 3 is wound around the coil bobbin 4 at position A in a direction indicated by an arrow, the winding start being indicated by Aa and the winding end by Ab, which then constitutes the winding start Ba at position B; the winding end Bb at position B successively constitutes the winding start Ca at position C, the winding end at this position being indicated by Cb.
- the winding start Aa at position A and the winding end Cb at position C correspond to the coil end portions 4 a and 4 b at the ends of the three coil bobbins 4 around which the stator coil 3 is wound in series.
- a series winding stator coil body 30 is formed.
- the three coil bobbins 4 around which the stator coil 3 is wound by the winding frame jig 20 of FIG. 1 constitute the U-phase.
- each of the other phases: V-phase and W-phase, is formed by three coil bobbins 4 .
- the number of coil bobbins 4 per phase (one of the U-, V-, and W-phases) is not restricted to three; it may also be two, four, etc.
- the coil bobbins 4 of the U-, V-, and W-phases are fitted onto stator teeth 2 of a stator teeth body 1 .
- Each phase only involves a pair of coil end portions 3 a and 3 b ; since there are nine coil bobbins 4 in total for the three phases, there are six coil end portions 3 a and 3 b in total extending from these coil bobbins, which is a substantial reduction as compared with the conventional structure, in which there are eighteen coil end portions.
- stator teeth body 1 formed as shown in FIG. 2 and equipped with the coil bobbins 4 is formed as shown in the exploded sectional view of FIG. 3; by forcing this stator teeth body 1 into a cylindrical yoke 5 shown in FIG. 6, a stator 10 is formed.
- a ring-like printed board 11 mounted to the stator 10 has six terminal patterns (not shown). Since the number of coil end portions 3 a and 3 b is small, it is possible to effect connector connection with the ring-like printed board 11 omitted. Further, the means for winding the stator coil 3 around the coil bobbins 4 is not restricted to a bar-like jig of FIG. 1; it is also possible to effect winding with the coil bobbins 4 mounted to an arcuate jig.
- the winding method and structure for stator coils of the present invention provides the following advantages.
